Comprising: a flexible conductor (10) that is flexibly bent; a shape-retaining conductor (20) that retains the shape; and a protective member (30) that surrounds the connection section (40) of the flexible conductor (10) shape-retaining conductor (20) and retains the connection section (40) in a linear shape, wherein one end section of the protective member (30) is fixed to the end section of the shape-retaining conductor (20).

Description

Wire harness
Technical Field
The present invention relates to wire harnesses.
Background
Conventionally, in a wire harness mounted on a vehicle such as a hybrid vehicle or an electric vehicle, the following are known: a shape-retaining conductor that retains its shape is used in a portion where flexibility is not required when mounted on a vehicle, and a flexible conductor that is flexibly bent is used in a portion where flexibility is required for connection to a device or the like. By using the shape-retaining conductor and the flexible conductor at appropriate positions, it is possible to improve space efficiency, reduce cost, and the like.
For example, patent document 1 listed below describes a wire harness using a single core wire as a shape-retaining conductor and a stranded wire as a flexible conductor. In this wire harness, a single core wire having a smaller diameter than the stranded wire is inserted into the shield tube, thereby suppressing the diameter of the shield tube to be small. The single core wire and the stranded wire are joined by ultrasonic welding by overlapping the conductor exposed from the insulating coating layer at the terminal portion of the single core wire and the conductor exposed from the insulating coating layer at the terminal portion of the stranded wire in a direction intersecting the extending direction of the two electric wires. The conductor of the single core wire is flattened into a flat plate shape, and the conductor of the stranded wire is joined to a flat surface formed by the flattening. The flattened portion has a width larger than the outer diameter of the single core wire, and therefore is not accommodated in the shield tube through which the single core wire is inserted. Therefore, the connecting portion between the single core wire and the stranded wire is disposed at a position exposed outward from the end portion of the shield tube.

< example 1>
Hereinafter, an embodiment embodying the present invention will be described in detail with reference to fig. 1 and 2.
The wire harness according to the present embodiment is mounted on a vehicle such as a hybrid vehicle, and is connected between a device mounted on a front portion of the vehicle and a device mounted on a rear portion of the vehicle. The wire harness of the present embodiment has a plurality of (only one shown) conductive wires W.
The conductive wire W is formed by connecting a flexible conductor 10, which is flexibly bent, and a shape-retaining conductor 20, which retains the shape, in the longitudinal direction. For example, the shape-retaining conductor 20 is used at a portion of the conductive wire W disposed under the floor of the vehicle body, and the flexible conductor 10 is used at a portion disposed in the vehicle interior. The conductor of the conductive wire W is made of metal (aluminum, aluminum alloy, copper alloy, or the like) and is formed to have a substantially circular cross section.
The flexible conductor 10 is a stranded conductor formed by stranding a plurality of metal wires, and is surrounded by an insulating coating layer 11.
The shape retaining conductor 20 is a tubular conductor composed of a single hollow metal tube. The outer diameter of shape retaining conductor 20 is somewhat larger than the outer diameter of flexible conductor 10.
The conductive wire W has a connection portion 40 that connects the flexible conductor 10 and the shape-retaining conductor 20. The flexible conductor 10 and the shape-retaining conductor 20 are joined so that the end of the flexible conductor 10 and the end of the shape-retaining conductor 20 overlap each other in a direction intersecting the extending direction of the conductive wire W.
An end portion of the shape retaining conductor 20 is provided with a joint portion (hereinafter referred to as a shape retaining conductor-side joint portion 21) that is crushed into a flat plate shape. The shape-retaining conductor-side engaging portion 21 is crushed so that both ends of the shape-retaining conductor 20 in the radial direction are in close contact with each other. The shape-retaining conductor-side engaging portion 21 is located closer to one end side in the radial direction of the shape-retaining conductor 20, and is located on one side of the center line of the shape-retaining conductor 20 as a whole. The shape-retaining conductor-side engaging portion 21 is substantially parallel to the center line of the shape-retaining conductor 20. The surface of the shape-retaining conductor-side joint portion 21 facing the centerline of the shape-retaining conductor 20 is formed as a joint surface 22 to be joined to the flexible conductor 10. The joint surface 22 is formed as a flat surface.
A stepped portion 23 is formed at an end portion of the shape retaining conductor 20 by forming a shape retaining conductor-side engaging portion 21. The step portion 23 has a step larger than approximately half of the diameter size of the shape retaining conductor 20.
A fixed portion 24 is provided at an end portion of the shape retaining conductor 20, and an end portion of a protective member 30 described later is fixed to the fixed portion 24. The fixed portion 24 is formed adjacent to the step portion 23 and has a substantially constant outer diameter. The fixed portion 24 is fitted to the inside of the fixing portion 32 of the protection member 30.
A joint portion (hereinafter referred to as a soft conductor-side joint portion 12) in which wires are welded to each other to form a block is provided at an end portion of the soft conductor 10. The flexible conductor-side joint portion 12 is formed in a flat substantially rectangular parallelepiped shape. The flexible conductor-side joint portion 12 is located at the center in the radial direction of the flexible conductor 10, and has steps formed on both sides in the radial direction (upper and lower sides in fig. 2).
The flexible conductor-side joint portion 12 is overlapped with the joint surface 22 of the shape-retaining conductor-side joint portion 21 and joined by, for example, an ultrasonic joining machine. By this ultrasonic welding, the contact portion between the flexible conductor 10 and the shape-retaining conductor 20 is joined to each other by metal bonding, and electrical connection is possible. In a state where the flexible conductor-side engaging portion 12 and the shape-retaining conductor-side engaging portion 21 are engaged, the center line of the flexible conductor 10 and the center line of the shape-retaining conductor 20 are substantially coaxial.
The wire harness includes a protective member 30, the protective member 30 surrounds a connection portion 40 between the flexible conductor 10 and the shape retaining conductor 20 and retains the connection portion 40 in a linear shape, and one end portion of the protective member 30 is fixed to an end portion of the shape retaining conductor 20.
The protective member 30 is a metal (aluminum alloy, copper alloy, stainless steel, or the like) cylindrical member (tube), and includes a surrounding portion 31 surrounding the connection portion 40 and a fixing portion 32 fixed to the fixed portion 24 of the shape-retaining conductor 20. The protective member 30 is linear and has a circular cross section with an equal diameter over the entire length.
The fixing portion 32 of the protective member 30 is provided at one end portion in the axial direction of the protective member 30. The fixing portion 32 has an inner diameter size one turn larger than the outer diameter size of the fixed portion 24, and covers the outside of the fixed portion 24.
The fixing portion 32 of the protective member 30 and the portion of the shape-retaining conductor 20 that is overlapped with the fixed portion 24 (hereinafter referred to as a tab portion 41) are partially subjected to plastic working, whereby the protective member 30 and the shape-retaining conductor 20 are fixed to each other. Hereinafter, a portion where the joint portion 41 is subjected to plastic working (a portion where the joint portion is fixed to each other) is referred to as a fixing portion 42.
The securing portion 42 is located at one end side of the protective member 30 in the axial direction, and is disposed apart from the connecting portion 40 by a predetermined distance. The fixing portion 42 is provided at one portion of the joint portion 41.
The fixing portion 42 is plastically deformed into a shape recessed outward and protruding inward by pressing the joint portion 41 from the radially outward side toward the radially inward side with a tool. The fixing portion 42 has a groove shape continuous in the circumferential direction of the joint portion 41. The securing portion 42 is a portion obtained by pressing the entire circumference of the joint portion 41 from the radially outer side.
In the fixing portion 42, both the fixing portion 32 of the protective member 30 and the fixed portion 24 of the shape retaining conductor 20 are compressed radially inward, and have a shape in which the outer peripheral surface side is recessed and the inner peripheral surface side protrudes. In the fixing portion 42, a convex portion 44 on the inner peripheral surface of the protective member 30 is fitted (intruded) into a concave portion 43 on the outer peripheral surface of the shape retaining conductor 20 and is locked in the axial direction.
The protective member 30 is covered with an insulating member 33. The insulating member 33 is a shrink tube or the like, and covers the entire length of the protective member 30. The insulating member 33 has a length dimension that surrounds not only the protective member 30 but also the entire length of the shape retaining conductor 20. The insulating member 33 covers the entire length of the protection member 30 and the shape-retaining conductor 20 together, and also serves as a covering member for the shape-retaining conductor 20. The insulating member 33 is in close contact with the outer peripheral surfaces of the protective member 30 and the shape-retaining conductor 20. Further, one end of the insulating member 33 is covered on the insulating coating layer 11 of the flexible conductor 10.
Next, the operation and effect of the embodiment configured as described above will be described.
The wire harness of the present embodiment has: a flexible conductor 10 that is flexibly bent; a shape-retaining conductor 20 for retaining the shape; and a protective member 30 that surrounds the connection portion 40 between the flexible conductor 10 and the shape retaining conductor 20 and retains the connection portion 40 in a linear shape, and one end of the protective member 30 is fixed to the end of the shape retaining conductor 20. According to this configuration, since the connection portion 40 between the flexible conductor 10 and the shape retaining conductor 20 can be prevented from being bent, the connection portion 40 can be protected.
The protective member 30 is made of metal, and has an insulating member 33 surrounding the protective member 30, and the insulating member 33 covers the entire length of the protective member 30 and the shape-retaining conductor 20. According to this configuration, since the insulating member 33 surrounding the protective member 30 also serves as a covering member for the shape-retaining conductor 20, the number of components and the number of steps can be reduced as compared with the case where the insulating member 33 of the protective member 30 and the covering member for the shape-retaining conductor 20 are separately provided.
< example 2>
Next, a wire harness of example 2 embodying the present invention will be described with reference to fig. 3.
The wire harness of the present embodiment is different from that of embodiment 1 in that it includes a shield member 51 surrounding a conductive wire 50. Note that the same components as those in embodiment 1 are given the same reference numerals, and redundant description thereof is omitted.
The wire harness of the present embodiment includes a conductive wire 50, and the conductive wire 50 is configured by connecting a flexible conductor 10, which is flexibly bent as in embodiment 1, and a shape-retaining conductor 52, which retains the shape, in the longitudinal direction.
The shape-retaining conductor 52 is a single core conductor made of one solid metal rod, and is surrounded by an insulating coating layer 53. The outer diameter of the shape retaining conductor 52 is smaller than the outer diameter of the flexible conductor 10.
A shape-retaining conductor-side joint portion 54 crushed into a flat plate shape is provided at the terminal portion of the shape-retaining conductor 52 in the same manner as in example 1. The shape-retaining conductor-side joint portion 54 is located closer to one end side in the radial direction of the shape-retaining conductor 52 as in example 1, and a surface facing the centerline side of the shape-retaining conductor 52 in the shape-retaining conductor-side joint portion 54 is formed as a joint surface 55 to be joined to the flexible conductor 10. Further, a step portion 56 is formed in the distal end portion of the shape retaining conductor 52 by forming a shape retaining conductor-side engaging portion 54 in the same manner as in example 1.
The flexible conductor 10 is a stranded conductor formed by stranding a plurality of metal wires in the same manner as in example 1, and is surrounded by an insulating coating layer 11.
The wire harness includes the protective member 30 as in example 1, and the protective member 30 surrounds the connection portion 40 between the flexible conductor 10 and the shape retaining conductor 52 and retains the connection portion 40 in a linear shape. The protective member 30 is a metal (aluminum alloy, copper alloy, stainless steel, or the like) cylindrical member (tube) as in example 1, and includes a surrounding portion 31 surrounding the connection portion 40 and a fixing portion 32 fixed to a fixed portion 59 of a shield tube 57 described later. The fixing portion 32 has an inner diameter size one turn larger than an outer diameter size of the fixed portion 59, and covers the outside of the fixed portion 59.
The shield member 51 includes a shield tube 57 surrounding the shape-retaining conductor 52 and a flexible shield member 58 surrounding the flexible conductor 10.
The shield tube 57 is formed of a long tube made of metal (for example, made of aluminum or aluminum alloy). The shield tube 57 is formed so as to pass the shape-retaining conductor 52 therethrough, and has a circular cross section. By forming the conductive wire 50 so that the portion inserted into the shield tube 57 is smaller in diameter than the flexible conductor 10, the shield tube 57 is kept smaller in diameter. The connection portion 40 between the flexible conductor 10 and the shape retaining conductor 52 is disposed at a position away from the end of the shield tube 57 to the outside.
Most of the shield pipe 57 extends in the front-rear direction along the underfloor of the vehicle, and both front and rear ends of the shield pipe 57 are disposed in the vehicle interior. The shield pipe 57 is bent along a predetermined pipe path.
A fixed portion 59 is provided at an end of the shield tube 57, and an end of the protective member 30 is fixed to the fixed portion 59. The fixed portion 59 is fitted to the inside of the fixed portion 32 of the protection member 30.
The flexible shielding member 58 is, for example, a braided member formed by braiding a conductive metal wire rod into a cylindrical shape, and has good bendability. Flexible shield member 58 is fixed to the end of shield tube 57 together with protection member 30.
The end of the flexible shield member 58 is sandwiched between the fixing portion 32 of the protective member 30 and the joint portion 41 where the fixed portion 59 of the shield tube 57 is overlapped. The joint portion 41 is partially subjected to plastic working in the same manner as in example 1, whereby the protective member 30 and the shield pipe 57 are fixed to each other.
As in example 1, the fixing portion 42 of the joint 41 is formed in a shape in which the fixing portion 32 of the protective member 30 and the fixed portion 59 of the shield pipe 57 are both compressed radially inward and are recessed on the outer peripheral surface side and protrude on the inner peripheral surface side. In the fixing portion 42, the concave portion 43 on the outer peripheral surface of the shield pipe 57 and the convex portion 44 on the inner peripheral surface of the protective member 30 are fitted in a state of sandwiching a part of the flexible shield member 58, and are locked in the axial direction.
As described above, in the present embodiment, similarly to embodiment 1, since the protective member 30 is provided, the protective member 30 surrounds the connection portion 40 between the flexible conductor 10 and the shape retaining conductor 52 and holds the connection portion 40 in a linear shape, and one end portion of the protective member 30 is fixed to the end portion of the shield tube 57, the connection portion 40 between the flexible conductor 10 and the shape retaining conductor 52 can be prevented from being bent, and the connection portion 40 can be protected. Further, since the end portion of the flexible shield member 58 is fixed to the end portion of the shield pipe 57 together with the end portion of the protective member 30, it is not necessary to fasten a fastening ring or the like for connecting the end portion of the flexible shield member 58 to the end portion of the shield pipe 57, and therefore the number of parts and the number of steps can be reduced.
< other examples >
The present invention is not limited to the embodiments described above and illustrated in the drawings, and for example, the following embodiments are also included in the technical scope of the present invention.
(1) In the above-described embodiment, the protective member 30 has a linear shape, but is not limited thereto as long as the surrounding portion of the protective member surrounding the connecting portion is linear, and for example, the protective member may have a shape in which a portion other than the surrounding portion is curved (e.g., L-shaped).
(2) In the above embodiment, the protective member 30 is made of metal, but is not limited thereto, and for example, the protective member may have a composite structure including a metal cylindrical portion and a synthetic resin insulating portion, the cylindrical portion having a cylindrical shape surrounding the connection portion, and the insulating portion covering an outer surface of the cylindrical portion. With this configuration, sufficient strength can be ensured by the metal cylindrical portion, and the insulating member can be eliminated, so that the number of components can be reduced.
(3) In the above embodiment, the fixing portion 42 is provided at one portion of the joint portion 41, but the present invention is not limited thereto, and the fixing portion may be provided at two or more portions of the joint portion.
(4) In the above embodiment, the protection member 30 is formed with a circular cross section having an equal diameter dimension over the entire length, but is not limited thereto, and the size of the cross section of the protection member and the like may be changed depending on the location, and for example, the surrounding portion and the fixing portion in the protection member may be different in diameter dimension.
(5) In the above embodiment, the flexible conductor 10 is a stranded conductor, but is not limited to this, and the flexible conductor may be a conductor composed of a braided wire obtained by braiding a metal wire material, for example.
(6) In the above-described embodiment, the shape-retaining conductors 20, 52 are formed as a tube conductor composed of one hollow metal tube or a single core conductor composed of one solid metal rod, but are not limited thereto, and any configuration may be used as long as the shape-retaining conductors are rigid conductors capable of retaining a shape.
(7) In the above-described embodiment, the fixing portion 32 of the protective member 30 and the fixed portion 24 of the shape retaining conductor 20 or the fixed portion 59 of the shield tube 57 are overlapped by plastic working, whereby the protective member 30 and the shape retaining conductor 20 or the shield tube 57 are fixed to each other.
(8) In the above embodiment, the shape of the shape-retaining conductor-side joint portions 21 and 54 is exemplified, but the shape of the shape-retaining conductor-side joint portions 21 and 54 may be any shape as long as they can be connected to the flexible conductor 10. For example, the shape-retaining-conductor-side joint portions 21 and 54 may be formed so as to be close to the radial center of the shape-retaining conductors 20 and 52, or the thickness-direction center of the shape-retaining-conductor-side joint portions 21 and 54 may be formed so as to substantially coincide with the center axes of the shape-retaining conductors 20 and 52. Alternatively, the shape-retaining conductor-side engaging portion 21 may be omitted, the flexible conductor 10 may be inserted into the shape-retaining conductor 20, and the shape-retaining conductor 20 may be crimped to the flexible conductor 10 so as to crush the shape-retaining conductor 20 radially inward.
